Visual diagnosis of pectus excavatum: An inter-observer and intra-observer agreement analysis.

BACKGROUND/PURPOSE: Among patients suspected of pectus excavatum, visual examination is a key aspect of diagnosis and, moreover, guides work-up and treatment strategy. This study evaluated the inter-observer and intra-observer agreement of visual examination and diagnosis of pectus excavatum among experts. METHODS: Three-dimensional surface images of consecutive patients suspected of pectus excavatum were reviewed in a multi-center setting. Interactive three-dimensional images were evaluated for the presence of pectus excavatum, asymmetry, flaring, depth of deformity, cranial onset, overall severity and morphological subtype through a questionnaire. Observers were blinded to all clinical patient information, completing the questionnaire twice per subject. Agreement was analyzed by kappa statistics. RESULTS: Fifty-eight subjects with a median age of 15.5 years (interquartile range: 14.1-18.2) were evaluated by 5 (cardio)thoracic surgeons. Pectus excavatum was visually diagnosed in 55% to 95% of cases by different surgeons, revealing considerable inter-observer differences (kappa: 0.50; 95%-confidence interval [CI]: 0.41-0.58). All other items demonstrated inter-observer kappa's of 0.25-0.37. Intra-observer analyses evaluating the presence of pectus excavatum demonstrated a kappa of 0.81 (95%-CI: 0.72-0.91), while all other items showed intra-observer kappa's of 0.36-0.68. CONCLUSIONS: Visual examination and diagnosis of pectus excavatum yields considerable inter-observer and intra-observer disagreements. As this variation in judgement could impact work-up and treatment strategy, objective standardization is urged. LEVELS OF EVIDENCE: III.

Dutch Lung Surgery Audit: A National Audit Comprising Lung and Thoracic Surgery Patients.

BACKGROUND: The nationwide Dutch Lung Surgery Audit (DLSA) started in 2012 to monitor and evaluate the quality of lung operations in The Netherlands as an improvement tool. This outline describes the establishment, structure, and organization of the audit by the Dutch Society of Lung Surgeons (NVvL) and the Dutch Society of Cardiothoracic Surgeons (NVT), in collaboration with the Dutch Institute for Clinical Auditing. In addition, the first 4-year results are presented. METHODS: The NVvL and NVT initiated a web-based registration, including weekly updated online feedback for participating hospitals. Data verification by external data managers is performed on regular basis. The audit is incorporated in national quality improvement programs, and participation in the DLSA is mandatory by health insurance organizations and the National Healthcare Inspectorate. RESULTS: Between January 1, 2012, and December 31, 2015, all hospitals performing lung operations participated, and a total of 19,557 patients were registered from which almost half comprised lung cancer patients. Nationwide the guideline adherence increased over the years, and 96.5% of lung cancer patients were discussed in preoperative multidisciplinary teams. Overall postoperative complications and mortality after non-small cell lung cancer operations were 15.5% and 2.0%, respectively. CONCLUSIONS: The audit provides reliable benchmarked information for caregivers and hospital management with potential to start local, regional, or national improvement initiatives. Currently, the audit is further completed with data from nonsurgical lung cancer patients, including treatment data from pulmonary oncologists and radiation oncologists. This will ultimately provide a comprehensive overview of lung cancer treatment in The Netherlands.

Early removal of the chest tube after complete video-assisted thoracoscopic lobectomies.

OBJECTIVE: Chest tubes induce morbidity such as pain, decrease mobility, increase the risk of infection, and prolong the length of hospital stays. This study evaluates a chest-tube protocol containing a high-drainage threshold and a short time period of drainage. METHODS: A retrospective study was performed with data collected from all elective complete video-assisted thoracoscopic (c-VATS) (bi-)lobectomies between March 2006 and December 2009. All patients had one chest-tube, postoperatively. The chest tube was removed if there was no air leakage and there was a drainage volume of 400 ml (24 h)(-1) or less. We aimed to remove the chest tube on postoperative day 1. RESULTS: This series consists of 110 lobectomies and six bilobectomies. The median duration of chest-tube placement was 1.0 day. In 58.8% of patients (confidence interval (CI) 95%: 49.5-68.0), the drain was removed within 24 h of operation and in 82.5% (CI 95%: 74.2-88.7) within 48 h. In six (6.2%) patients, subcutaneous emphysema developed while the drain was still in place, and was treated with removal of the drain. Persistent air leakage was seen in four (3.4%) patients. One (0.9%) persisting pneumothorax was diagnosed. A pneumothorax after removal of the drain was not diagnosed. No major complications developed in 98 patients (84.5%). The median day of discharge was postoperative day 4. CONCLUSIONS: This study shows it is safe, after c-VATS (bi-)lobectomy, to remove the chest tube within 24 h in 58.8%, and within 48 h in 82.5% of patients. As was also shown in other studies, this leads to shorter length of hospital stays, lower costs, and most importantly, reduces patient morbidity without the added risk of complications.
